How To Mount A Swing Between Two Trees. If they don’t touch the ground with their legs or if they are touching it with their knees, you need to adjust the length of the swing by shortening or lengthening the ropes. To determine spacing of the swing set itself, measure down from the top bar to the ground and multiply the measurement by 2.
Measure for the right height. The pipe you mention sounds plenty big enough. The holes should be positioned at the front where the hammock will hang so the hardware will not be twisted sideways when the hammock is hung between them.
Add 1 foot to this measurement and you have the distance you need between your trees.
This is accomplished by wrapping two straps or pieces of rope around the tree. There is debate about the safest way to install a tree swing, but in general there are two main approaches: Then connecting the two straps together with metal clips and another strap. This is how far away the swing set needs to be from all other objects.
